Walk About

You and up to two willing creatures within range project your astral bodies out into the current Plane you inhabit; you cannot move from your current plane for the duration of this spell. The material body you leave behind is unconscious and in a state of suspended animation; it doesn't need food or air and doesn't age.

Your astral body resembles your mortal form in almost every way, replicating your game statistics and possessions with the exception of your speed: while under the effects of this spell, your speed equals 300 ft. flight for purposes of mechanics.

Your astral form can freely travel through the Plane and can pass through objects without penalty, unless otherwise stated. Your astral form is a separate incarnation. Any damage or other effects that apply to it have no effect on your physical body, nor do they persist when you return to it.  You return to your body without difficulty as long as the personal possession is still within 5 feet of it.

The spell ends for you and your companions when you use your action to dismiss it or a full day has passed since casting the spell. When the spell ends, the affected creature returns to its physical body, and it awakens.

The spell might also end early for you or one of your companions. A successful dispel magic spell used against an astral or physical body ends the spell for that creature. If a creature's original body or its astral form drops to 0 hit points, the spell ends for that creature.

If you are returned to your body prematurely, your companions remain in their astral forms and must find their own way back to their bodies, usually by dropping to 0 hit points.
